Non-water Lavatory Flushing Device with Flushing Pump

ABSTRACT

A non-water lavatory flushing device consists of a electrical four-way valve, which one of its exit is connected with the exit of the side wall of the valley at the back of the toilet pan for collecting the feces. The three exits are connected with the central part of the toilet pan, feces collecting box and the flushing liquid collecting box through a feces dispersing pipe, a feces collecting pipe and a urine collecting pipe. The non-water lavatory flushing device of the invention uses a four-way valve to replace the feces dispersing pipe magnetic valve, feces collecting pipe magnetic valve and urine collecting pipe of the prior art. The dispersed feces liquid and urine in the feces dispersing pipe, feces collecting pipe and urine collecting pipe is controlled by the four-way valve respectively. Then the structure is simplified and the cost is decreased. Furthermore, as the four-way joint is cancelled, the problem of wrong flowing of the leaving liquid is solved. Thus, it could be avoided that the feces plasm flow into flushing liquid collecting box or the limited clean urine is discharged along the feces collecting pipe and this is advantaged to improve the flushing effect.

FIELD OF INVENTION

The invention relates to a lavatory flushing device having the specialstructure. The above structure has a flushing pump, so it is unnecessaryto use the water as the flushing fluid.

BACKGROUND OF THE INVENTION

The applicant of the invention is as same as the internationalapplication (the publication number is WO02/68764), in which a kind offlushing lavatory is published. It consists of toilet pan, crushing pumpand circuit control device. The stool crushing pipe is set at the bottomof the toilet pan and connected with the outlet of the crushing pump ofthe toilet pan. A magnetic valve is set on the stool crushing pipe. Thestool collecting pipe is set at the bottom of the toilet pan and has amagnetic valve. The other end of the stool collecting pipe is open andcan discharge the sewage. When flush the lavatory, under the control ofthe circuit control device, the flush liquid forms a circulation in thepath generated by the toilet pan, crushing pump, stool crushing magneticvalve, stool crushing pipe and toilet pan and flushes the stool in thetoilet pan into the crushing pump to crush. Then the stool liquid willmix with the flush liquid and become a gruel liquid; the circuit controldevice makes the magnetic value open and the crushing pump will rotateand make the sewage in the toilet pan discharged outside through thecrushing pump, magnetic valve and stool collecting pipe. The water canbe saved greatly by using the circulated flushing structure and theinvention has the good effect of water saving. In addition, the urinecollecting device, liquid medicine adding device, double-pump flushingdevice and automatic stool and urine identification device are set. Theabove structures combine together and configure the no headwaterlavatory flushing system. It has the functions of sanitary flushing, nobad smell and controllable discharge and meets the requirement ofenvironment protection.

But after having been used for some time it is found that the lavatoryhas some shortcomings. As the occupied space of the feces dispersingpipe, feces collecting pipe, urine collecting pipe and the magneticvalve of the above pipes and four-way connector is larger, thus theinstallation is complicated, the maintenance is difficult. Especially,as it is easy to leave the liquid in the four-way connector, so it makesthe different magnetic value opens and leads to the connecting ofdifferent pipeline. Then the remaining liquid will flow to the placethat it should not go. For example, the feces plasm flows into theflushing fluid collecting box, or the limited clean urine dischargesthrough the feces collecting pipe.

With the detailed description of the embodiments of the inventionreferring to the figures we can see the characters and advantages of theinvention obviously.

In order to understand the invention better, we site the PCT applicationhaving the same applicant as this invention with the publication numberof WO2/68764 to be the reference.

WO2/68764 published a kind of flushing lavatory, as shown in FIG. 6. Itincludes a human detection device 2, the circuit control device 1, atoilet pan 3, a dispersing and centrifugal device 5, a upper flushingliquid flushing pump 28, a flushing liquid collecting box 26, a fecescollecting box 25, an automatic deodorant liquid adding device 50 andmultiple pipeline device.

The dispersing and centrifugal device 5 consists of a dispersing toolpan 4 and a centrifugal blade 6 wheel mounted on the same rotating shaftand a motor 7, which is mounted at the valley 31 of the toilet pan, usedfor driving the rotating shaft. The upper flushing fluid flushing pump28 is mounted at the internal or external of the flushing liquid box 26and this makes the upper flushing liquid easy to be pumped out. The exitof the upper flushing fluid flushing pump is connected with shedding 16at the front side 32 of the toilet pan 3 through a pipeline 20. Themultiple pipeline device consists of a feces dispersing pipe 8 and amagnetic valve 12 mounted on it, a feces collecting pipe 22 and amagnetic valve of the feces collecting 9 mounted on it and a urinecollecting pipe 10 and a magnetic valve 11 of the urine collecting pipemounted on it. The entry of feces dispersing pipe 8, feces collectingpipe 22 and urine collecting pipe 10 is connected with the exit 33 ofthe side wall of the back valley 31 at the toilet pan for collecting thefeces through a four-way connector 40, and the exit is connected withthe shedding 13 of the middle part 34 of the toilet pan, the fecescollecting box 25 and flushing liquid collecting box 26 respectively.The automatic deodorant liquid adding device 50 includes a medicine pot17, medicine guiding 19, for which one end is connected with the bottomof the medicine pot 17 and the other end is connected with the urinecollecting pipe 10 and a medicine adding magnetic valve 15 mounted onthe medicine guiding pipe 9. A feces discharging pump 24, its entry isset at the bottom of the feces collecting box 25 and its exit isconnected with a feces discharging pipe 23 extending out from the fecescollecting box 25 and the exit of pipe 23 is connected with aaccumulating container. The circuit control device 1 is electricallyconnected with the motor 7, upper flushing liquid flushing pump 28 andthe motor of feces discharging pump 24, magnetic valve of the fecesdispersing pipe 12, magnetic valve of the feces collecting pipe 9,magnetic valve of the urine collecting pipe 11, medicine adding magneticvalve 15 and human detection device 2. The circuit control device 1 is acommon chip microcomputer. The human detection device 2 is set at thesuitable position in the lavatory and is used for changing the detectedsignal of having people or not in the lavatory into the electric signaland then transfers it to the circuit control device 1. The detectiondevice 2 could be the photoelectrical detecting device mounted in thelavatory and also could be the passive human infrared detector or thepressure sensor mounted under the floor of the lavatory and also couldbe the position switch set at the lock or cross-pin of the lavatory orother different kinds of detection devices only as its state could showif there is a person in the lavatory. For example, as the user entersthe lavatory, the human body will barrier or reflect the light comingout from the photoelectrical detection device and it makes the state ofthe detection device changed. The infrared ray from the human body canchange the state of passive human infrared detector. When a person stepson the floor, it can change the state of the pressure sensor under thefloor. When a person locks the door, it can change the open or closestate of the position switch. All the above working state of thedetecting device could illustrate if someone is using the non-waterflushing device in the lavatory.

As shown in FIG. 7, the statistical chart of time of peeing anddefecating used by the way of peeing and defecating automaticidentification in the circuit control device of the non-water flushinglavatory in the prior art. The chart shows the time of a person usingthe lavatory, peeing and defecating by plane rectangular coordinates.The chart is drawn by sampling the lavatory using time of severalhundreds of people and it can show the using regulation of a commonlavatory. The longitudinal coordinate is the differential of the numberof people using the lavatory and the using time and it is shown inpercentage. The horizontal coordinate is time for using the lavatory.There are two curves in the chart and the actual line shows theregulation of using time and number of people and the imaginal lineshows the percentage of people finish using the lavatory between thetotal number of people before a certain time.

Form FIG. 7 we can see the three peak values are men peeing, womenpeeing and defecating. The imaginal line shows that 90% of people usingthe lavatory happens in the time of 0-t₀ and almost all for peeing.

From the effective test we can see the tester could not finishdefecating in less time than t₀, then we can get the conclusion: such atime t0 is existing and in such time no people could finish defecating.According to the actual test the value of t0 is between 1 minute and 1and a half minute.

The above conclusion help us to find a automatic method for identifyingthe defecating or peeing by the time for using the lavatory. The programfor identifying the defecating or peeing is set in the circuit controldevice 1 and is connected with the detection device 2.

Referring to FIG. 8 which shows the logic chart of the defecating orpeeing automatic identification of the non-water flushing lavatory inthe prior art. The circuit control device 1 having the program ofidentifying the defecating or peeing, not only can start the procedureof flushing the toilet pan 3 according to the people's leaving signalprovided by the detection device 2, but also can start timing accordingto the signal of user entering the lavatory provided by the detectiondevice 2. The said timing process ends until the detection device 2provides the signal of user leaving. The circuit control device 1identifies the defecating or peeing according to the long and short timerecorded by the timing device. That means when the time using thelavatory is shorter than t0, it can be determined that the user doesn'tdefecates. But as some user takes long time when pees so this way couldnot identify the defecating or peeing so correctly, but it can identifythe number of users not defecating. The above method could not be calledas “way of automatic identification of peeing” because user leaving thelavatory in t0 may not only pee, but also may do nothing.

Referring to FIG. 6, as the non-water flushing lavatory works and thedefecating or peeing begins, the circuit control device 1 starts timingaccording to the defecating or peeing beginning signal sent by thedetection device 2. When defecating or peeing, the circuit controldevice 1 makes the urine collecting magnetic valve 11 open and the urinewill flow into the flushing liquid collecting box 26 through thedispersing and centrifugal device 5, urine collecting pipe 10. Theseparation of urine and feces is realized. In the process of urinecollecting, the circuit control device 1 makes the medicine addingmagnetic valve open and this lets the medicine liquid 18 from themedicine pot 17 flow into urine collecting pipe 10 through medicineliquid guiding pipe 19 and mix with the collected urine and then flowinto the flushing liquid collecting box 26 and the change from themedicine liquid to flushing liquid is realized. When the user leaves thelavatory, the circuit control device 1 judges it was peeing by theidentification program according to the defecating or peeing endingsignal sent by the detection device 2, it will start the motor 7 of theupper flushing liquid flushing pump 28 and the motor of dispersing andcentrifugal device 5 and upper flushing liquid in the flushing liquidcollecting box 26 will be pumped by the upper flushing liquid flushingpump 28 and it flow into the shedding 16 at the front part 32 of thetoilet pan 3 and flush it. Then it is sucked into the back valley 31 ofthe toilet pan 3 for collecting feces by the blade wheel 6 of thedispersing and centrifugal device 5 with the urine together. And then itwill be pumped out into the urine collecting pipe 10 through the exit 33at the side wall of the back valley 31 and flow back nit the flushingliquid collecting box 26. If it was defecating, the circuit controldevice 1 will close the urine collecting pipe magnetic valve 11 andstart the upper flushing liquid flushing pump 28 and delay a certaintime. The flushing liquid in the flushing liquid collecting box 26 willbe pumped out by the upper flushing liquid flushing pump 28 and flowinto the shedding 16 at the front part 32 of the toilet pan 3 along theflushing liquid pipe 20 and into the toilet pan 3. After those thecircuit control device 1 starts the motor 7 of the dispersing andcentrifugal device 5 and makes the feces dispersing pipe magnetic valve12 open and the feces will be dispersed by the tool pan 4 of thedispersing and centrifugal device 5 and it will mix with the flushingliquid and become the gruel liquid. With the action of the blade wheel 6of the dispersing and centrifugal device 5, a forced circulation on theannular path composed by the toilet pan 3, the back valley 31 of thetoilet pan 3 for collecting feces and the feces dispersing pipe 8. Afterthat, the circuit control device 1 closes the feces dispersing pipemagnetic valve 12 and opens the feces collecting pipe magnetic valve 9and this makes the gruel feces liquid flow into the feces collecting box25 through the feces collecting pipe 22. So there is a little gruelfeces leaving in the bottom of the toilet pan 3. At this time onlystarting the upper flushing liquid flushing pump 28, the flushing liquidwill flow into the toilet pan 3 with the action of the upper flushingliquid flushing pump 28 and the toilet pan 3 could be flushed cleaneasily. Use this kind of non-water flushing lavatory, the flushingliquid used for flushing the feces each time could decrease from theoriginal 6-12 liter to about 0.5 liter and good flushing effect could beensured.

From the above description we could know that as the prior art ofnon-water flushing lavatory works, its urine collecting pipe magneticvalve 11 feces dispersing pipe magnetic valve 12 and feces collectingpipe magnetic valve 9 have the same entry that is the exit 33 at theside wall of the back valley 31 of the toilet pan for collecting fecesand different exits and its time for opening and closing are different.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Below is the detailed description of the invention, non-water flushingdevice in lavatory with flushing pump.

The first embodiment of non-water flushing device in lavatory withflushing pump as shown in FIG. 1. The main differences between FIG. 1and FIG. 6 lines in that the of non-water flushing device in lavatoryhaving an upper flushing liquid flushing pump 28, as shown in FIG. 1 hasa four-way electrical control valve 80, which replaces the urinecollecting pipe magnetic valve 11, feces dispersing pipe magnetic valve12 and feces collecting pipe magnetic valve 9 of the non-water flushingdevice in lavatory having flushing pump, as shown in FIG. 6 and at thesame time the four-way shedding 40, as shown in FIG. 6 has beencanceled. Except this, the structure of non-water flushing device inlavatory as shown in FIG. 1 and FIG. 6 is almost same, so no detaileddescription will be given.

The shell of the four-way electrical control valve 80 has a cross fluidentry and three flow exits at the longitudinal direction. The aboveentry is connected with exit 33 at the side wall of the back valley 31of the toilet pan 3 and the three exits are connected with the shedding13 at the middle part 34 of the toilet, a feces collecting box 25 and aflushing liquid collecting box 26 through a feces dispersing pipe 8, afeces collecting pipe 22 and a urine collecting pipe 10. There is a Lfluid pathway in the spool of the electrical control valve 80. The crosspathway of L pathway always goes in with the cross fluid entry of thefour-way electrical control valve 80. The four-way electrical controlvalve 80 could be a four-way electric ball valve and it is the priorart.

When the non-water flushing lavatory with a flushing pump as shown inFIG. 1 works, the electrical control device 1 can make exit 33 at theside wall of the back valley 31 of the toilet pan 3 connect with theurine collecting pipe 10, feces dispersing pipe 8 and feces collectingpipe 22 respectively in different time by four-way electrical controlvalve 80. So the proper work of the non-water flushing lavatory with aflushing pump as shown in FIG. 1 could be realized. Referring to theabove detailed description of the work process of the non-water flushinglavatory with a flushing pump as shown in FIG. 1, the ordinarytechnician in this filed could understand how the non-water flushinglavatory with a flushing pump as shown in FIG. 1 works and no otherdescription is needed.

The second embodiment of non-water flushing device in lavatory withflushing pump as shown in FIG. 1. Compare with the non-water flushinglavatory with a flushing pump as shown in FIG. 1, the non-water flushinglavatory with a flushing pump as shown in FIG. 2 has a lower flushingliquid flushing pump 27 and a low flushing liquid pipeline 21 connectedwith the exit of the lower flushing liquid flushing pump 27. The lowerflushing liquid flushing pump 27 is mounted in the flushing liquidcollecting box 26 and is in the lower flushing liquid. The exit ofpipeline 21 is connected with the flushing open end 35 at the middlepart 34 of the toilet pan. The motor of lower flushing liquid flushingpump 27 is connected with the circuit control device 1 electrically.

When the above non-water flushing device in lavatory with flushing pumpworks, under the control of circuit control device 1, the lower flushingliquid flushing pump 27 extracts the sediment in the lower flushingliquid of the flushing liquid collecting box 26 and it goes up andreaches the flushing open end 35 in the lower flushing liquid throughthe lower flushing liquid pipeline 21. And then it blowouts toward theback of the toilet pan 3 with the leaving urine and feces to flush thetoilet pan. After that the upper flushing liquid flushing pump 28extracts the flushing liquid from the flushing liquid collecting box 26and it goes up and reaches the open end 16 at the front part 32 of thetoilet pan 3 through upper flushing liquid pipeline 20 and then theflushing liquid enters into the toilet pan 3 and also blowouts towardthe back of the toilet pan 3 with the leaving urine and feces to flushthe toilet pan again. So with the action of the lower flushing liquidflushing pump 27 and the upper flushing liquid flushing pump 28, thetoilet pan 3 could be flushed clean without urine sediment left. And thesediment of the lower flushing liquid in the flushing liquid collectingbox 26 could be consumed and it will not be accumulated more and more.

The third embodiment of non-water flushing device in lavatory withflushing pump as shown in FIG. 3. Compare with the non-water flushinglavatory with a flushing pump as shown in FIG. 2, the non-water flushinglavatory with a flushing pump as shown in FIG. 3 has a one-way valve.The exit of the lower flushing liquid flushing pump 27 is connected withthe one-way valve 14 through the lower flushing liquid pipeline 21 andthe exit of the one-way valve 14 is connected with the open end 13 atthe middle part 34 of the toilet pan and the feces dispersing pipe 8. Aliquid level sensor of the feces collecting box 29 and a liquid levelsensor of the urine collecting box are used in the above lavatory andthe two sensors are connected with the circuit control device 1.

The fourth embodiment of non-water flushing device in lavatory withflushing pump as shown in FIG. 4. Comparing it with the non-waterflushing device in lavatory with flushing pump as shown in FIG. 3, thedifference is that a overflowing dummy plate 36 is set in the flushingliquid collecting box 26 and the lower flushing liquid flushing pump 27and the upper flushing liquid flushing pump 28 in the flushing liquidcollecting box 26 are mounted at the left and right side of theoverflowing dummy plate 36 respectively. Near the bottom of the flushingliquid collecting box 26, the urine collecting pipe 10 is connected withthe left side of the overflowing dummy plate 36. Setting the overflowingdummy plate 36 in the flushing liquid collecting box 26 could made theprecipitated upper flushing liquid in the left side of overflowing dummyplate 36 overflow into the right side of plate 36 over it. Theprecipitated upper flushing liquid is most suitable to be the finalflushing liquid when the non-water flushing device in lavatory withflushing pump of the invention works each time. Except this, as theprecipitated upper flushing liquid in right side of overflowing dummyplate 36 will no longer to produce sediment, so it is unnecessary tomount the upper flushing liquid flushing pump 28 in the upper part ofthe flushing liquid. Then it can be avoided that the upper flushingliquid flushing pump 28 could not pump out the flushing liquid whenliquid level of the precipitated upper flushing liquid reduced.

The fifth embodiment of non-water flushing device in lavatory withflushing pump as shown in FIG. 5. Comparing it with the non-waterflushing device in lavatory with flushing pump as shown in FIG. 4, thedifference is that the flushing liquid collecting box 26 is divided intoleft flushing liquid collecting and right flushing liquid collectingwhich are connected with each other through a middle pipe 38 at theupper part of it. Using the pathway generated by the middle pipe 38, aurine processing unit 39 could be set in and it can process the urine,such as filtration, decolourization, purification, disinfection,contaminant separation and so on. The lower flushing liquid flushingpump 27 and the upper flushing liquid flushing pump 28 are mounted in orout of the two left and right flushing liquid collecting boxesrespectively. Near the bottom of the flushing liquid collecting box 26the urine collecting pipe 10 is connected with the left flushing liquidcollecting box and the liquid level sensor 30 of the flushing liquidcollecting box is mounted in the right flushing liquid collecting box.Thus, the precipitated upper flushing liquid in the left flushing liquidcollecting box can flow into the right flushing liquid collecting boxthrough the middle pipe 38. The precipitated upper flushing liquid ismost suitable to be the final flushing liquid when the non-waterflushing device in lavatory with flushing pump of the invention workseach time. Except this, as the precipitated upper flushing liquidflowing into the right flushing liquid collecting box will no longer toproduce sediment, so it is unnecessary to mount the upper flushingliquid flushing pump 28 in the upper part of the flushing liquid. Thenit can be avoided that the upper flushing liquid flushing pump 28 couldnot pump out the flushing liquid when liquid level of the precipitatedupper flushing liquid reduced. Otherwise, for the fourth embodiment asshown in FIG. 4, as the precipitated upper flushing liquid in the leftside of overflowing dummy plate 36 overflows into the right side ofplate 36 through it, a large amount of flushing liquid foam willoverflow into the right side of dummy plate 36 together. This will leadto the inaccuracy of the flushing liquid level transduced by the liquidlevel sensor 30 of the flushing liquid collecting box. But for the fifthembodiment as shown in FIG. 5, the possibility for producing thisproblem is more less. Furthermore, a urine processing unit 39 could bemounted in the middle pipe 38 and it can process the urine, such asfiltration, decolourization, purification, disinfection, contaminantseparation and so on. And then the non-water flushing device in lavatorywith flushing pump of the invention could have the same good flushingeffect as the water flushing lavatory.

As shown in FIG. 1 to FIG. 6, the feces discharging pump 24, the lowerflushing liquid flushing pump 27 and the upper flushing liquid flushingpump 28 are mounted in the feces collecting box 25 and the flushingliquid collecting box 26. For the invention, the feces discharging pump24, the lower flushing liquid flushing pump 27 and the upper flushingliquid flushing pump 28 also could be mounted outside of the fecescollecting box 25 and the flushing liquid collecting box 26 and at thistime the exits of the feces discharging pump 24, the lower flushingliquid flushing pump 27 and the upper flushing liquid flushing pump 28should be connected with the correspondent outlets of the fecescollecting box 25 and the flushing liquid collecting box 26respectively.
